【Abstract】 In this paper, the concept of the cone efficient quasiconcave set is introduced and a relationship between the R+m-strictly quasiconcave set and the R+m-efficient quasiconcave set is discussed. Under conditions that a compact set is cone efficient quasiconcave and its efficient point set is closed, we prove that the efficient point set is connected.更多还原
